There is no science I can point to but I feel using language that way makes it as if the skill has become part of your identity. Makes it hard to detach. So that I insult Ruby or Apple and now I am insulting you. Google is dying means a big part of your self is becoming obsolete. I am a "pythonista/rubyist/haskeller" encourages tribal thinking. Them vs Us. I find this also explains much about flamewars. I don't like.

To avoid that I prefer to say I know Z. I use X instead of I am a X user. I am most skilled in Y not a Y'er. I really like A. It is still hard to see A die but I don't need to defend every affront as if I was the one insulted. I allow only a few things to help define part of my identity. Doing this actively, also triggers to conscious how much I don't want to slip into tribalism or stagnation.

And by being ok with confusion it means I don't fear new things, by being confused it means I'm learning, by being curious I'll actively seek to put my self beyond my ability.
